  • the present invention relates to a vehicle control panel for controlling a function for a vehicle.
  • Vehicles typically comprise numerous electrical systems for controlling various functions. In modern vehicles more and more functions are incorporated and the electrical systems consequently grow in size and in complexity.
  • Some vehicles employ electrical touch panel interfaces for controlling the electrical systems and their associated functions.
  • Touch panel interfaces provide a neat appearance and versatility in selecting functions, but they are sensitive to for example exposure to water or other liquids.
  • a physical switch may be used for making a selection for a function in a vehicle.
  • a physical switch is commonly employed in a door control panel of a vehicle for controlling the position of rear view mirrors or the opening and closing of the vehicle windows.
  • a switch may be adapted to close or open an electric circuit.
  • the electric circuit is often located below the switch button which is moved by a user for making a selection.
  • an actuator presses against a printed circuit board (PCB) comprising the electric circuit which controls the function. The pressing of the actuator against the electric circuit on the PCB causes the electric circuit to close to thereby operate the function.
  • PCB printed circuit board
  • this type of physical switch comprises many separate parts such as the actuator, the switch button, a PCB comprising the electric circuit, and thus requires some space where it is mounted.
  • the electric circuit on the PCB which is commonly mounted below the switch button is sensitive to liquid. For example, it may happen that liquid is unintentionally spilled inside the vehicle or that water enters the interior of the vehicle from the outside (e.g. rain). This liquid may find its way to the PCB and cause damage to the electric circuit.

  • the present invention is based on the realization that the electric circuit can be integrated in the switch cap by printing it on a surface inside the switch cap or embedding it in the material of the switch cap. In this way, the electric circuit is protected from liquid by the switch cap itself. Furthermore, printing the electric circuit inside the switch cap or embedding it in the switch cap eliminates the need for the PCB traditionally arranged under the switch cap. Thus, in this way the space under prior art control panels which way occupied by PCB and related electronics is, with the inventive concept, made available for other uses.

  • FIG. 7 illustrates a further possible configuration of electrical connection pads 706 is shown in FIG. 7 which illustrates a pair 700 of electrical connection pads 706 .
  • the electrical connection pads 706 are somewhat comb-shaped and are interleaved with each other but not in contact with each other. The interleaving of the comb-shaped electrical connection pads 706 enables improved electrical contact between the electrical connection pads 706 in the pair 700 when a electric circuit closing member overlaps with both the electrical connection pads 706 in the pair 700 .
  • the control unit may include a microprocessor, microcontroller, programmable digital signal processor or another programmable device.
